I

The tally strip mechanism is mounted on a supporting frame comprisingupright arms 26 and 27 and a connecting cross bar 28. Said support maybe mounted on the cross rod 12 of the'pla-ten frame and fixed to saidrod near the'right-hand end thereof so that the rotary holders for thetally work sheet which are mounted on said frame are above the tallyplaten section 17. The d-elivery roll holder or tally strip spool 29 ismounted on a rod or shaft 30 and the other tally strip spool orreceiving roll holder 31 is mounted on a rod or shaft 32 below thedelivery holder, the shaft32 bearing ro; tat-ably in the arms 26 and 27.Arranged between the right-hand end of the roll holder 31 and thesupporting arm 26 is a pinion which-is secured to the shaft 32 as by apin 3a passing transversely through the hub of said pinion and throughsaid shaft. Outsidethe arm 26 a similar pinion 35 is mounted on theoutwardly projecting end of the shaft 32 and is suitablyvfixed thereto,

The extreme end portion of-the'shaft, indi 'cated by 32, maybe reducedin diameter and flattened at oppositesides to receive a short crank arm36 which is formed with a hole having two stralght opposite sides thatfit over the portion 32, said crank arm being secured inplace by'aheaded screw 37 A- smaller screw 38 passes through the outeri end of thecrankarm and is threaded into 7 the pinion 3-5, thus fixedly connectingsaid! pinion with the shaft 32. The pinions 33 and 35 are respectivelyconnected through pinions or idlers 3'9 and 40 with the gear wheels 19and '21, said idlers being preferably mounted to, rotate loosely on theframe rod 12. It will be observed that two parallel trains of geardevices are provided, said trains being arranged at opposite sides ofthe annulus 20 and that said trains connect the ratchet wheel 18 withthe receiving roll holder 31 and the tally platen section 17,

The parts heretofore described correspond or may correspond, except forminor differences, with the construction disclosed in 'Clio B. Yaws-saidprior application, Serial No. 762,1H. There is one difierence ofimportance, however, between the present construction as thus fardescribed and said prior construction, namely, no tally feeding devicesare provided for cooperatively engaging with the tally platen section inthe present instance, the tally being advanced or; fed by the turning ofthe receiving roll holder 31 on which the tally strip or righthand worksheet is wound. The turning of the tally platen section 1'?simultaneously with the turning operation of the roll holder 31 throughthe gear "connections between the two parts facilitates the advancemovement o f the tally strip which doesnot have to drag over amotionless platen section or paper support. Said platen section turns asthetal'l'y strip advances but this turning of the tally platen sectiondoes not, properly speaking, result in a feeding operation of the tally.The two platen sections or work sheet supports and the tally receivingholder are adapted to be actuated by novel line spacing devicescomprising sets of nisms operative by a single hand piece or actuator,these devices being controllable by novel controllingmeans including apreventive device so that either the main platen section 16 may beadvanced alone and independently of the other platen section and theroll holder 31, or on the other hand, the section 16 together with thetally platen section and the holder 31 may be turned or line spacedtogether. Spring mounted roller 'detents 4-1 and 12 cooperaterespectively with the ratchet wheels 18 and 22 to maintain them and theparts respectively connected and controlled by them in adjustedpositions follow-mg and between lnie spacing operations. The sets ortrains of paper advancing mechanisms aforesaid comprise pawls or pawlmembers 43 and i l arranged side by side and adapted for cooperationrespectively with the ratchet wheels 18 and 22, said pawl members beingloosely suspended from a bearing in the formof a headed shouldered screw"or stud 45 which is'fixedly secured by a nut 46 to a radial supportingarm 47 which is loosely mounted on a sleeve 48 fixed tothe right-handend plate 10 of the platen'fr'ame and concentric with the platen axle 14which passes through it. The two pawls. are loosely confined. betweenthe head of thescrew 45 and the arm 17 but are spaced leftward away fromsaid arm by the hub portion 43" of the pawl member 13. The mounting ofthe pawl members 43 and 1 1 comprising the arm 47 is like that of theface "of the pawl member 13 and then is bent leftward forming a shoulder49, the shoulder portion extending partly overthe front edge of the pawlmember 4st. The extreme upper end portion of the spring is bent backwardand e'ngagesvin a hole 51 in the pawl member 14. The tendency of saidspring is constantly to press said pawl member 44 rearward and when itis free toexa "ert its pressure it will move said pawl member until thelimit of such movement is reached as determined by the engagement of theshouldered portion 49% of the spring "withthe'frontface of the pawlmember 43.

The independent movement of the p member 44 under the influence of thespring is, however, controlled and regulated b 1 vices hereinafterdQSCIlbQd. I

, a. r 1 bon strip yfiand the tally strip 71 11). some this rock shaft.being the same as is usually provided on the Remington machine forsupporting the right-hand paper ,finger.

The usual paper finger is replaced in the present instance by the finger68 which not .only exercises a controlling function on the pawl member44 but also is adapted to act as a paper guide to properly direct theright-hand marginal bill sheet into cooperation with the annulus 20. Therock shaft 69 that supports said finger 68 is rotatably mounted, theleft-hand end portion of said 'rockshaft bearing in a bracket 70-screwed to the front of the platen frame bar 11,

(Fig. 1) while the right-hand end portion of said rock shaft bears inthe righthand endbar l and rojects slightly outward beyond said endliar. The projecting end portion has fixed to it by a screw 71 arearwardly extending crank arm 7 2 to the free end of which is anchoredthe lower end of a coiled draw spring 73, the upper end of said drawspring, being anchored to one of the platen shift devices 9. Said drawspring tendshconstantly to swing the crank ,arm 7 2 upward, this upwardmovement being limited by a stop pin 74 projecting outward from the endbar withwhich stoppin the crank arm is normally in engagement as shownin Fig.3. The action of the spring 73, it will be understood, tends toturn the upper faces of the rock shaft 69 forward and to swing thefinger 68.. forward so that said finger 1s normally mainta ned away ifrom the annulus as shown 1n said Fig.

affect the associate work sheet or tally strip.

It will. be understood that the spring 49 opposes the spring 7 3 andtends to swing the pawl member 44 inward toward its ratchet wheel butthe spring 4-9 is considerably weaker than the spring 73 so that it isnot effective to overcome the latter.

in order to overcome the spring 73 and render the spring 49 effective toswing the pawl member 44 into a normal position such that it will act onits ratchet wheel when the hand-piece G4 isactuated, devices areprovided for automatically swinging the finger or preventive device 68rearward so as to render it ineffective and cause it to release the pin67 andthe pawl member 44. Said devices operate automatically] duringvtravcling movements of the carriageor'platen mally inclines forward anddownward as shown in Fig. 3 and is adapted to cooperate with astationary cam member or actuating device 7 6 which is shown in detailin Fig. 2. Said cam member is formed with slots 77 which receive screws7 8 bywhich the cam member is adjustably secured to the top plate of themachine. Said cam member is ,providedwith a rearwardly off-set portion79, the right-hand end of whichis inclined downward as indicated at 80,forming a cam which is in the path of the finger 75. This camis soarranged that the finger 75 will engage with it when the travelingcarriage has moved so far to the left that the lefthand portion of theplaten section 17 has entered the printing field or been broughtopposite the point at which the type bars strike when actuated. Afterthe fingerengageswith the inclined face 80 farther leftward movement ofthe carriage will cause "the finger to ride up over said face onto theoff-set portion 79 and this action of the finger will turn the rockshaft 69 .and swing the finger 68 toward the platen, bringing the partsto the position shown in Fig. 5. This movement of the finger 68withdraws it from the pin 67 which leaves the pawl 44 free to be swungrearward by its spring 49 until arrested by the contact of the off-setportion 49 with the front face of the pawl member 43 as shown in Fig. 5.With the pawl members. thus positionedan actuation of thehand-piece 64will effectively actuate both pawl members, causing them to cooperatewith their respective ratchet wheels and simultaneously advance bothplaten sections and also the tally receiving roll holder, thus advancingor line spacing both the main and tallyvwork sheets. The offset portion79 isof such length that it will operate through the finger/75 to renderthe pawl member '44 operative so long as the tally strip remains in theprinting field and until the end'of the carriage travel toward the leftis reached. When the carriage is retracted the finger75 willmovebackward along and over. the off-set portion and down over theincline 80 and the snring 73 will become effective to swing the fingeror preventive device 68 forward to the Fig. 3 position where it willmaintain the pawl member 44 in inoperative position.
